抛出:

IllegalAccessException

IllegalArgumentException

InvocationTargetException

NoSuchMethodException

SecurityException

public static void foreachClass(Consumer<Class<?>> processor,
                                Function<String,Boolean> filter,
                                String... packages)

                                                Object... objects)

类型参数:

S - 必须是接口

T - extends S

参数:

o - object

objects - 需要扩展出来的对象，只扩展接口

返回:
